yii弹出层插件怎么用 [ 2.0 版本 ]

index.php代码：

<?= app\widgets\GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
       ['class' => 'yii\grid\CheckboxColumn'],
       'title',
        [
            'attribute' => 'cate',
            'format' => 'raw',
            'value' => function($model){
                if($model->cate==0){
                    return Html::a(未设置, ['select', 'get' => 'cate' , 'id' => $model->id], ['class' => 'a-select','id'=>cat.$model->id]);
                }
                return Html::a(\common\models\Article::$cates[$model->cate], ['select', 'get' => 'cate' , 'id' => $model->id], ['class' => 'a-select','id'=>cat.$model->id]);
            }
        ],
        [
            'class' => 'app\widgets\ActionColumn',
            'buttons' => [
                'updates' => function($url, $model){
                   return Html::a('<span class="glyphicon glyphicon-pencil"></span>', $url);
                },

            ],
            'template' => '{updates} {view} {delete}',
        ],
    ]
])?>

我想在这里面把修改做成弹出层的，但不知道弹出层插件怎么用？请各位教我一下 在这里面该怎么加弹出层，谢谢各位了
